Sophos Updates

[Mike Kercher]

I know we had this discussion a few months back about automating the update
of Sophos monthly.  I emailed the folks at Sophos and they replied with a
script.  The script they provided checks date stamps and only downloads if
necessary.  I have modified it somewhat to fit my needs.  If anyone would
like a copy of the script in its original form, I'd be happy to post it to
the list or off-list if that's more desirable.
